SOLAR SYSTEM

Detailed explanation-1: -Some asteroids are round, some are elongated, and some even have a satellite. A comet also orbits the Sun, but unlike an asteroid, it’s composed of ice and dust. So, when a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and/or has a tail.

Detailed explanation-2: -The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron.

Detailed explanation-3: -Asteroids are small rocky planetoids. while comets are formed of frozen gases held together by rocky and metallic material.

Detailed explanation-4: -Specifically, comets and asteroids have much higher concentrations of iridium and other heavy metals than Earth’s crust has.

Detailed explanation-5: -Unlike asteroids which are made up solely of rock, comets are made of a mix of ice, rock and gas. They’re also leftovers from the formation of the solar system and orbit the sun. But because of the way they’re made, as they get closer their ice and dust begin to melt which gives it a beautiful tail.
